I think your thought experiment is 2000 fighters meeting an air born threat anywhere in Germany. 2000 fighters alone could not protect Germany. From the UK the USAF could attack from the North Sea and across France from Italy and North Africa they could attack all of South Germany France and Eastern Europe. To protect Germany from all possible avenues of attack would require more than 10,000 aircraft. To take a break to build up such a force would mean Germany did not have any industry or cities in place. I base this on the difficulty the UK had in repelling the luftwaffe in 1940.Their job was to kill the Luftwaffe, the bombers were really just bait to bring them up. That was the great innovation by the great (and always underestimated) Doolittle.
He realised that just chasing them away was pointless, the Luftwaffe pilots lived to fight another day and that would let it steadily build up strength, eventually to level that could overwhelm any escorts.
They had to be killed, chased and killed, setting in train the attrition on pilots and machines that finally killed the organisation.
Take a 'thought experiment'. Say the Luftwaffe had managed to build up to (say) 2,000 fighters over Germany...that would have ended the USAAF's daylight campaign, real fast.
At that sort of numbers they could have (a) intercepted the escorts as they headed towards rendezvousing with the bombers, forcing them to drop tanks and taking them out of the game, (b) staged multi pronged attacks, with enough to draw off the escorts and still enough left to hammer the bombers.
The USAAF then would have had to have built up far greater numbers of escort fighters to counter that (with escorts escorting other escorts at various points).

In practice Old Skeptic is right - all te LW had to defend against was the long range escorts (P-38 and P-51). The number of US long range Groups went from three (December 1944) (20, 55 and 354FG's) to 10 by the end of May - which meant 3 long range escort groups per 11 Bomb Groups (30 mile string) in each of three divisions. 2000 LW fighters attacking where THEY chose to engage limits the numbers of long range escort groups to defend - one to two Maximum.
Park only had to deal with raids across the channel, after the LW tried a raid from Norway and got hammered all raids from there stopped, I say "only" but this was a considerable task. Park had more than 30-40 minutes warning that a raid was building up but knowing a raid was building didn't tell you where it was coming from. The 8th could attack across any German coast+ France and Holland. Other forces could attack across the Alps. All the Americans would have to do is modify their tactics. Instead of a deep penetration raid just raid the periphery of Germany with more escorts until Germany concedes the territory. The problem isn't solved until the escorts are massively outnumbered wherever they are and that cannot be done all over Germany with 2000 AC. This is of course hypothetical and ignores the fact that Germany had to defend the French coast, transport links to France the eastern oilfields as well as defending the eastern front with RussiaThanks to their extensive radar (and radio listening) network, which stretched into France and Holland, they had hours of warning of USAAF raids from whatever direction. In 1940 Park had 30-40 mins warning and had to react to that, which he did masterfully. They didn't need 10,000 fighters, 2,000 with well trained pilots, with good tactics, would have made the 8th's job a heck of a lot harder.
There are sometimes I find forums contradictory, some time ago I suggested that the Luftwaffe would have had more success if they engaged the escorts earlier forcing them to drop their tanks. I was told that post war both sides admitted that this would merely result in the LW being wiped out in a different place, I cant look back over my previous posts to find it though..
I either did, or would have agreed with you. I still believe the LW gave the 8th FC too much leash by virtue of "Avoid the fighters" order from Goering as well as not sending separate flights of 109s to attack the fighter escorts in one pass and evade beginning in mid 1943.. It was one thing for Hunter to order the fighter groups to not drop their tanks unless extremely necessary - and another for the group CO's to tell their guys 'do what you think best'
The P47 also had considerable range with its larger drop tank. 2000 aircraft may be able to defend a particular place in central Germany but not the whole of Germany.
Even with larger 150 gallon drop tanks for the P-47D-11 through -15 available during Big Week, the Jug was limited to Hannover/Stuttgart combat radius, way short of forcing the LW hand for most central Germany targets. The -20 reached the 56th FG in March but not in numbers. It had the ability to carry two 100 gallon tanks, but wasn't available in quantity until April/May at which time the P-51 and P-38s with greater range were performing all the middle to deep escort duties.
So, given 2000 day fighters and the pilots to fly them results in four effective 'LuftFlotte Reich's" and greatly reduces the barriers to putting 500 fighters in the air to attack local escorts (two max P-51 or P-51/P-38 FG's for one entire bomb division, say attacking Augsburg or Magdeburg, giving a 5:1 local ratio. In that sector, then, one full LF Reich is available and perhaps 50% from one adjacent sector and 25% from another places 350+ s/e heavily armed fighters to attack the now un escorted 10-12 bomb groups at will, including landing and refueling and re-engaging.
Even defending against the 15th as well as the 8th AF the blood bath would exceed the US ability to continue daylight bombing politically.
The air battles, while favoring 8th and 9th AF FC from mid February through May, were fought against a daily strength Order of Battle of perhaps 400-500 day fighters.
The combat radius of a SE is quite small, after climbing to 25,000ft and fighting for 20 mins it needs to find some where to refuel. With only 2000 aircraft you must surrender all the extremities like the northern ports the Ruhr and the southern industrial areas. To outnumber the escorts all over Germany by sufficient AC to enable heavy enough losses to be inflicted requires many more than 2000 aircraft. The bombers themselves were not unarmed and did inflict losses on the LW even on completely unescorted raids. Where would you place 2000 planes to repel raids on Hamburg Berlin Peenemunde and Stuttgart?
Thanks to their extensive radar (and radio listening) network, which stretched into France and Holland, they had hours of warning of USAAF raids from whatever direction.
Exactly as placed for the Defense of the Rich as far as sectors go - just reinforce the fighter strength 4X.
Another factor. The US was producing crews, fighter pilots and the respective aircraft at peak production. Impossible to reinforce the 8th and 9th AF FC much because there really weren't enough airfields to expand beyond April, 1944 and shifting resources from MTO (When reinforcements are required to support 15th AF) isn't feasible. Ditto the PTO/CBI which was still suffering lack of front line fighter strength for its own projects.
In summary - the notion that the LW could actually stick 1500 more fighter pilots into LF Reich in spring 1944 is ludicrous - But since the question is What If, I agree OldSkeptic's POV.
The P47 was replaced by the P51 but could surely still be used with 150gal tank for penetration or withdrawal.
Yes - the 150 centerline tank for the pre-P47D-20 with wing pylon was in fact the dominant Penetration and withdrawal escort - up to Stuttgart or Hannover. In April 1944 there were about 13 active operational P-47 Fighter groups in both 8th and 9th AF performing escort duties under 8th AF operational control. At the same time there were five Mustang groups with the 352nd making the sixth in Mid April plus three P-38 FG's performing long range and target escort.
Tactically that means that perhaps 650 Jugs, 250 Mustangs and 150 Lightnings are scheduled and perhaps 75% of the P-38s and P-51s are 'effective' after early returns.
I said 10000 to defend Germany, the scenario you are describing isn't defending Germany but a few places furthest from the UK. I disagree with your numbers a little, if you have 2000 fighters can 850 be available to defend Augsberg without leaving huge areas with no cover at all. If the LW did magic up 1500 extra fighters then the USA must keep them pinned down somehow or they will go to Normandy in which case what is politically acceptable changes.
In terms of the effect of the P-38 one thing that I think is worth noting is what the Luftwaffe hoped to use to destroy bombers; The "Zerstoerer" a word meaning "Destroyer" was meant to be used to destroy enemy bombers. (Me 110 and latter Me 210C/Me 410A). Zerstoerers were meant to be fighter bombers that strafed up and bombed enemy runways and ground born aircraft to supress enemy fighters, they were also to use their fire power (which got to 4 x 20mm and 2 x 30mm canon on the Me 110G) to dispatch enemy bombers. Furthermore the idea was to use outsize long range weapons such as 30mm, 37mm even 50mm canon and 20cm rockets to snipe of bombers with stereoscopic range finder equipped gyro sights at ranges the 0.50 inch Browning was considerably less effective. (German gyro sights seem to have started with this in mind). The Me 110 and Me 410 apart from greater fire power than the single engine fighters also possessed greater range but were only about 7.5% to 5% slower.
Whatever the P-38's limitations against the Luftwaffe single engined fighters it may have had a greater effect on its twin engine fighters.
By the time the bombers cross the coastline the relative options for the bomber course narrows down considerably, but the primary tactics of assembling the bomber stream in a somewhat contiguous series of bombers groups was followed with rare exception. When multiple targets were selected during the ramp up phase in February through May to replace P-47 groups with Mustangs, even separate target branches were delayed until well into Germany.
.....
This is a mission profile to ensure defeat. The original proposition is that the LW could defend Germany with 2000 fighters. This shifted to the LW defending against only the 8th AF on deep penetration raids. Now we have the 8th committing suicide repeating serious mistakes over and over until they are told to stop.By the time the bombers cross the coastline the relative options for the bomber course narrows down considerably, but the primary tactics of assembling the bomber stream in a somewhat contiguous series of bombers groups was followed with rare exception. When multiple targets were selected during the ramp up phase in February through May to replace P-47 groups with Mustangs, even separate target branches were delayed until well into Germany.
If I could give you a mission that represents a typical day in the life of the 8th, select 24 April. Three Task Forces with 1st BD leading as 1st TF, 2nd TF/2nd BD next and finally 3rd BD next as 3rd TF in trail.
All the bombers crossed the coastline NW of Paris, proceeded to Stuttgart then set a course for Munich, Gablingen and Freidrichshafen. At Stuttgart, the target escorts P-38s and P-51s arrive. The 4th FG (mustangs) are sweeping in front with intent of STAYING with the 1st TF as Penetration escort to Augsburg - but make contact north of Stuttgart with JG 11. The next relay for target support for 1st TF isn't due until Augsburg.
Looking at the map, the bombers stay 'connected' all the way through Stuttgart and part way to Ulm, then the 3rd TF, escorted by the shorter range P-38s (all three FG's) turn se toward Friedrichshafen.. then a little later the now tail end 2nd TF B-24s turn for Gablingen as the 1st TF continues toward Augsburg to Erding (Ne of Munich) thence south and then back to the west under Munich and begins bomb run on Landsberg and Oberphaffenhofen. The 352nd and 354th FG and 363rd FG cover Gablingen strike leaving the 1st TF completely uncovered (by plan) for 15 minutes between Ulm and Augsburg - and are attacked by the first elements of nearly 250 s/e day fighters. The 355th and 357th arrive on-time north of Augburg and immediately engage.
After all targets are bombed the reciprocal track for all bomb groups is northwest toward Frankfurt where as many of the Mustangs and Lightnings with fuel reserves continue escort until R/V with P-47s of the Withdrawal escorts.
My scenario is in place for a realistic appraisal of what would have been possible - as follows:
The 56th FG swept in front of 1st TF prior to R/V with 4th FG at Stuttgart. 56th Alone, with several P-47 groups in trail in close escort but running low on fuel as they approach Stuttgart. The 4th FG is inbound as is the 20th/55th and 364th P-38 FG's. The 352nd, 363rd, 354th also inbound but further away, and last are 355th and 357th. All the Target escort fighters are on a more direct course (not parallel to the bombers).
Assuming that 2000 day fighters implies 4X locally placed to augment the actual defense, then:
If LW controllers could draw on eight Gruppes instead of two and hit the 56th and 4th at Stuttgart there are perhaps 20 minutes in which they have the US fighter escort at a severe disadvantage. Don't even go after the bombers yet, just engage the US escorts with significant air superiority at the point of attack. The 1st TF is now completely stripped and subject to persistent attacks from those fighters emerging or not involved with the 4/56 FG engagement. 100 s/e fighters beginning attacks from Stuttgart past Ulm.
The second attack occurs against the 355th and 357th 100 miles northwest of Augsburg with perhaps two Gruppes. This fight would be more even but the outcome is certain. The ability of the two mustang groups to achieve R/V and perform escort is out the window because of low fuel. Additionally this attack could be sourced from Kassel to Mulhausen - presumably from another 4x reinforced defense sector, leaving the Munich sector able to put up 500+ fighters to attack from Ulm all the way to and around Munich... against bombers that were unescorted.
The real result against LW around Munich was shooting down or forcing to Sweden of 27 B-17s for the loss of 50 s/e and t/e day fighters of which 42 were awarded to the P-51s of the 355th and 357th for the loss of six over Munich plus two more strafing around Stuttgart.
IMO in this scenario the German fighter losses would be as great as the destruction of US fighters but more importantly it would be possible to shoot down 100 B-17s and B-24s on a given day... and the 8th AF could not survive that kind of repeated losses politically.
IMO this is a reasonable scenario that would be catastrophic to D-Day air superiority plans if a.) LF Reich could actually achieve 200o experienced pilots in January 1944 and b.) could replenish at least 70% of the attrition
I agree entirely (good scenario) and there is an additional factor. The great successes the Luftwaffe achieved in late '43 was also because they could use their heavily armed twins. As the US escorts got more range they were obliterated, putting more pressure on the SE fighters.
In your scenario (I call it the 'Park/drgondog' scenario), provided they can strip away the escorts earlier this still leaves the Luftwaffe their twins to cause havoc.
Analogous to Park using the Spits against the 109s thus creating the space for the Hurricanes to get through to the bombers, we have the SE Luftwaffe fighters stripping away the US escorts to let the big twins get through to the bombers.
Airfighting is three dimensional, time after time we see a well placed squadron (or less) causing huge destruction of a much larger group of fighters. Park's tactics were not about getting Spits into dogfights with the 109s (anything but, he didn't want them to do that it was hit and run he wanted), it was about disrupting them with good bounces. Causing them to lose formation, move away from the bombers, lose altitude, burn fuel, etc (and if they had drop tanks then...drop them) and fighter pilots being fighter pilots to get into pointless chases after being bounced. That was what he meant by 'stripping the escorts away'.
So it wasn't, if done well, necessary for the Luftwaffe to use huge numbers of their SE fighters against the US escorts to strip them away. It was the tactics that mattered more.
Remember what Park faced. Little warning time, towards the end of the BoB ridiculous escort/bomber ratios (3:1, even 5:1 at times), yet he, with good tactics, still managed to inflict crippling losses on the bombers all the time.
Numbers, of course, are important, but good tactics can multiply the effectiveness of what you have got. The Luftwaffe had the technical capability (and greater fighter numbers would have been very useful, natch) but not the tactical capability to use what they had as effectively as they could have done.
Brilliant as Dowding and Park were they nearly lost when the LW concentrated on raids against Radar and Airfields. PArk was able to strip away the escorts when the objective, London, was clear. The Me109 had fuel to fight over London for, 5 minutes Park only had to make the escorts use burn 5 minutes of fuel and he would eventualy have the bombers alone regardless of the ratio. During the BoB Germany came no where near replacing their material losses while the RAF was replacing losses of aircraft although pilots were another matter. In 1944 Germany was struggling to provide pilots planes and fuel, even starting with 2000 planes and pilots they would lose because the allies had more and could more easily replace them.
I think Bungey (His book "Most Dangerous Enemy") pretty much has debunked that common mythology. Only one airfield (Manston) was ever put out of operation.
You might consider checking out the operations of the 9th Air Force P-38 groups, i.e. 367th, 370th and 474th Fighter Groups. The 367th and 370th operated the P-38 into early 1945 and the 474th stayed with the P-38 through to war's end. These units did see action against German fighters.
